1. 1. Performance of 2-18 GHz RF Switches Implemented in Chip & Wire Technology : Analysis of switch topologies, bias networks and an in-depth EM analysis of bondwires

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Gustav Eliasson; [2023]
   Keywords : RF Switch; PIN diode; Chip Wire Technology; Wide Bandwidth; High isolation; Single-Pole-Single-Throw; Single-Pole-Double-Throw RF Switch; PIN diode; Chip Wire Technology; Wide Bandwidth; Single-Pole-SingleThrow; Single-Pole-Double-Throw; RF-omkopplare; PIN-diod; Chip Wire Tekonologi; Bredbandig; Hög isolation; Enkelpolig-enkakast; Enkelpolig-dubbelkast;

   Abstract : The ability to control the path a signal takes through microwave circuitry is crucial when designing RF systems. The component that allows for the control of the signal path is called a switch, and it is the microwave component that this thesis will focus on. READ MORE

3. 2. Antenna Arrays for Dual-Frequency Harmonic Radar Application

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Venkatesh Raja; Mohammad Zafar Mohammad; [2023]
   Keywords : Technology and Engineering;

   Abstract : The aim of this thesis is to design two patch antenna arrays for dual-frequency harmonic radar application, one for the transmitter and the other for the receiver. The arrays are used to track the Bogong moth that migrates from the countryside to the Australian Alps during spring. READ MORE

4. 3. Numerical Simulations of Resonant Tunnelling Diodes

   University essay from KTH/Skolan för teknikvetenskap (SCI)

   Author : Love Sundström; Alexander Holmström Janeld; [2023]
   Keywords : Quantum mechanics; numerical methods; resonant tunnelling diode;

   Abstract : In this thesis, four different numerical techniques are implemented for the purpose of simulating resonant tunnelling diodes (RTDs). The chosen methods were: piecewise constant transfer matrix (TMM-C), piecewise linear transfer matrix (TMM-L), quantum transmitting boundary method (QTBM), and the Crank-Nicolson method (CN).

   Keywords : Shading; half-cell module; efficiency; PV facility; photovoltaic; solar energy; Matlab; simulink;

   Abstract : Solar photovoltaic energy has gained great importance in the last couple of years, as its costs getlower and the total installed capacity increases. As a result of this, new technologies are arisingwithin the field, with the objective of increasing performance and reducing costs. READ MORE

6. 5. Optimization of two high-performance size-exclusion chromatography methods with diode-array detection for protein quantification and purity assessment

   University essay from Lunds universitet/Centrum för analys och syntes

   Author : Camilla Lane; [2023]
   Keywords : Method qualification; Protein concentration; Protein Purity; High Performance Size exclusion chromatography; Quality control; Analytical chemistry; Biology and Life Sciences;

   Abstract : Background: There is a need to develop methods of determining concentration and purity for two new affinity ligands, protein T and protein H, in order to ensure the quality of an industrial production of said proteins. Aims: To develop a High Performance Size Exclusion Chromatography, HPSEC, method to determine concentration and purity of protein T and to improve an existing HPSEC method for concentration and purity determination of protein H that show selectivity, display linearity between peak area and injection amount and give repeatable results.
